NASCAR and Electric Cars: A Response to Bill Nye

Bill Nye is getting a lot of press lately by suggesting NASCAR ought to be racing electric cars.  I was rather disappointed with the reaction from NASCAR fans, as many dismissed the suggestion offhand, or offered ad hominem attacks on Nye. Firing off Twitter insults only reinforces the stereotype of NASCAR fans as […]

The Digital Dashboard

Those of you of a certain age may remember these odd looking flat black vinyl things called ‘records’. Records are analog devices. A groove is cut into the vinyl. A stylus rides along the groove and translates the wiggles in the groove into an electrical signal, which is then transmitted to a speaker, which turns it into a vibration (which, when pleasant, we call “music”.)

A Band Aid for NASCAR’s Tire Bleeding Problem

There are three things you don’t mess with in NASCAR: engines, fuel and tires.

Tuesday, NASCAR handed down a P5 penalty – the penultimate penalty on the books – to Ryan Newman’s 31 team. Crew Chief Luke Lambert was suspended six races, fined $125,000, and Newman and his owner Richard Childress were each docked 75 points. The tire specialist and team engineer were suspended for six races as well. RCR is appealing the penalty, but I wager they’ve got an uphill battle.

NASCAR’s made its stand loud and clear in the last few weeks. Tire bleeding will not be allowed. If you persist in trying, they’ll come down hard on you.

How Fast Would NASCAR Cars Go at Daytona without Restrictor Plates?

Doug Yates was guest on Dave Moody’s SiriusXM Speedway last week. He brought up a conversion you hear a lot in the week before Daytona and Talladega. Every 25 horsepower in the engine translates to about a 1 second decrease in lap times. Dave did the math: Removing the plates would increase the engine by 450 horsepower. Four hundred and fifty more horsepower equates to 18 seconds off the lap time, assuming all other things equal. That last part was a very important qualification. It will come back to haunt us in a moment.

The Flap over Roof Flaps

Why Roof Flaps? Roof flaps (the invention of which I detail in my book The Physics of NASCAR) help keep cars on the ground.  This is necessary because of Bernoulli’s law, which says basically that: Faster-moving air exerts less pressure. Slower-moving air exerts more pressure. A wing develops lift because the […]
